features of the genetic code

Question 1

what are intons

Answer 1

sections of dna that dont code for amino acids

Question 2

what are exons

Answer 2

sections of dna that do code for amino acids

Question 3

what are the 3 features of the genetic code

Answer 3

-non-overlapping
-degenerate
-universall

Question 4

what does degenerate mean

Answer 4

meaning more than one triplet codes for the same amino acid ,this reduces impact of mutations

Question 5

what does universal mean

Answer 5

some triplets of bases code for the same amino acid in all organisims,this means genetic engineering is possible

Question 6

what does non-overlapping mean

Answer 6

each base in a gene is only one part of one triplet of bases that codes for one amino acid, therefore each triplet is read as a descrite unit this is an advantage if a point muation occurs it will only affect one codon and therefore only one amino acid
